That 92MPG for the diesel Accord is the conversion from L/100km to MPG (Imperial), in US gallons it is 76MPG.

In that case, 120 mpg may not be doable, but 100 mpg would be.

Even still, for a full size car like the Accord, that's impressive. Now they just need to make a similarly sized car with the same engine, same frontal area, a .16-.18 drag coefficient, interior stripped of hundreds of pounds of useless fluff, and charge $15-20k for it. Acceleration, top speed, and FE would all improve a bit, while keeping the same or lower manufacting cost.

I drive an EV every day and it only cost about $600. It's a bicycle with an electric assist motor. It cruises 20 mph with a range of 15 miles. Charge time is about 3 hours.
